Hide the error messages by redirecting them to /dev/null.
Nothing else.

Don't know. According to Ralf Brown's Interrupt List,
INT E6h is only used by DOSEMU, the IBM ROM BASIC interpreter
and CP/M-86, the latter two are rather uncommon these days.
Maybe your program requires a crazy driver program?

If you haven't the driver program under NT, the program will
crash there the same way as it does under DOSEMU. The difference
is that NT doesn't print a message when it receives a bad
INT E6h request.
